The pilot reported that because of the left 10- to 15-knot quartering headwind, on short final approach he descended using airspeed about 5 knots faster than normal. The airplane bounced upon touching down on the runway, and then it began drifting toward the runway’s edge. Despite the pilot’s efforts at stopping the drift, the airplane veered off the side of the runway and rolled onto an adjacent grassy area. As the airplane decelerated in the grass, the airplane rolled into a 1-foot-deep trough and nosed over. This event resulted in breaking the windshield, bending the engine mounts, vertical stabilizer and rudder, and other airframe damage. The pilot further reported that no mechanical malfunction or failure occurred with the airplane during the accident flight.
